Analysis of low streamflows on Cape Breton Island Nova Scotia.: En37-582/1978E-PDF

"1, 3, 7, 10 and 30-day, annual and summer low-flow frequency analyses were performed for 11 hydrometric stations on Cape Breton Island, Nova Scotia. A Gumbel III theoretical frequency distribution was employed with the parameters being estimated by the method of maximum likelihood. When this method failed to give a solution then the method of smallest observed drought was used. For the three long-term stations analyses of the most recent 15 years of record were also performed for the annual and summer periods as an indication of the accuracy of using stations with short term records. The data and the 140 frequency curves are displayed on 34 linear vs probability scale plots by a CALCOMP plotter. A regression analysis may be undertaken in the future between the 1:25 and 1:100-year summer low-flow values and various physiographic and climatic parameters with a view to developing a technique for estimating low flows of various durations for ungauged watersheds"--Abstract, page i.
